IMPROVEMENT lN SKVLIGHT-COVERS.

CASE H.

To all whom it may concern Be it known that I, GEORGE HAYES, of thecity, county, and State of New York, have invented an Improvement inCovers for the Roofs of Metallic Structures, of which the following is aspecification:

The principal object of this invention is to perfectly prevent snow anddust from working through the hinge-joints of covers closing theopenings in the roofs of glazed metallic 'structures. It consists in thecombination of a ledge formed on the-cap-plate, which is usuallyprovided on such a roof, and an overhanging lip so arranged on the backpart of the cover that it will come in contact with the ledge before thecover is fairly closed, in order that the farther movement of the coverwill cause the lip to press firmly against the ledge, and thereby soetfectually close the joint that dust and snow will be absolutelyprevented from pass ing through it.

In the accompanying drawing, Figure l is a top view of a skylight havinga cover made according to my invention. Fig. 2 is a section of the sametaken lengthwise through the cover. Fig. 3 is a transverse sectionthereof, and Fig. 4: is a detail view of the cover illustrating itsimproved joint.

Similar letters of reference indicate corresponding parts in the severalgures.

A A are the bars that support the panes of glass. B are the cross-barsthat sustain their end edges. They may be of the usual form. E is thecover. It is hinged or pivoted at the upper end to the upper part of theroof by pins P, and it shuts down toward the lower opposite edge of theroof. Along its sides are pieces d d that overlap the adjacent bars AA,and protect the joints between them and the cover. The cap C of the roofoverhangs the hinge-joint of the cover, and excludes rain and moisturefrom it. The ends of the cap are covered by pieces that extend along theupper bar B, and project over the edges of the glass panes restingthereon, so as to shed rain and moisture onto them. The cap has formedon its edge, which overhangs the hinged end of the cover E, a narrowledge, a, which'extends inward, as shown in Fig. 2. From the back partof the frame of the cover there extends perpendicularly upward a piece,c, which has on its upper edge a lip, c, that laps over the ledge a,just mentioned, when the cover is closed and forms a very tight jointtherewith.

As the cover closes the lip e comes in contact with the ledge a sometime before the cover is shut,` and, therefore, the continued closing ofthe cover draws the lip hard down on the ledge, and forms thereby a verytight joint, and very perfectly excludes dust and snow.

This joint is of the utmost importance, as heretofore it has been foundalmost impossible to entirely exclude dust and snow from entering thehinge-joint of roof-covers.

What I claim as my invention is The combination of the lip e on the backpart ofthe cover, with the ledge c on thephap C of the roof,substantially as and for the'purpose herein set forth. y
